Ton/Z whom it may concern:

Be it known that I, JOHN W. CURRAN, a citizen of the United States, and a resident of ewpo'rt, in the county of Campbell and State of lieinueky, have invented certain new and useful improvements in Safety-Appliance Rivet-Bolts, of which the followingis a specification.

My invention is an improvement in safetyapplianee rivet-bolts especially intended for use on railway-cars; and the invention consists in certain novel constructions and coIn-' binations of parts, as will be hereinafter de- In the. drawing, Figure 1 illustrates my invention in connection with a grab iron. Fig. Zillirstratesthe invention in connection with abrake-statf stand. Fig. 3 shows the invention in. connection with an air-pipe clamp. Fig. 4 shows the improved bOltSlIi connection with a sill-step. Fig. 5 illustrates,

Fig. 6 is a side view of'an unthreaded boltin connection with a portion of a car, the latter being shown in section. Fig. 7 is a similar view,tl1c bolt being threaded. Fig.8 is a side view of the bolt previous 'tobeing riveted. Fig. 9 is a side view, and Fig. 10 is ancnd view, of the bolt, showing a keyapplied.

The object of'thc invention is. to simplify the present methods of applyinggrab-irons, sill-steps, uncoupling lever brackets, stakepockets, air-pipe clamps, retaining-valves, brake-stall" stands, &c., to steolfreight-ears. The present methods when one ofthe steps, clamps, or the like becomes broken HOCGSSl-I in. order to get at the rivets for cutting out the same.

My invention seeks to provide for re lacing auyof the devices held by thesafety- )olts without necessitating going inside the car or anymovcmcntof the freight, so that in a few the ear out of the train and without getting Repairs of this character are now made under conditions that make them very expensive for the railroads, as the cars must be taken to the repair-track, frequently causing a delay of twenty-four to forty-eight hours, and the importance of ready repairs that the Government imposes a hcavyfine on any railroads whose inspectors are detected running cars by terminals with defective safetyaplniances.

' to secure the irons in place "The present improvement facilitates the makin 'of repairs, so that man'y'repairs may bemat e which'would not otherwise'be madeunder existing circumstances, so that its to.

adoption will help the railroads as welljas ad- Vance the aims of the Government. By my invention I proyide a safety-bolt permanently in connectionwiththe cars, 'so

that when grab i'rons,-:-sill-steps, &c.', become broken they can be easily removed and re-' Placed.

As shown,.the"bolt Amay be" slotted, as shown at A, to receives. key B, 'or the slot may be omitted, as shownat A, Fig.4, and the 'bolt be threaded to receive a-nutC, as illustrated ini-thefsaid Figgj'l, for-securing the'-- grab-iron jin' lace.-""--Thr'oughout thecone struction T the olts are shouldered -'at a' to:

These irons have-openings fitting over the bolts,- and when so fitted, as shown in the figures, nuts C may; be alpplied,;as shown in ig. l, or the-keys ma e driven home, as-shown Figs.2, 9, an 10, 9o

The construction is simple, can be economically applied, and will resultin a great savingof time and nmncy.

It is found in practice that bolts and rivets rco securing grab or other irons rarely, if ever,

become broken, and bymaking the bolts peri i mancntly. in connection with the cars 1 pro-- vide for the ready substitution of new-irons whenever desired. ic5 Icln-im l h 1.
